Abstract
Provided is a method for manufacturing a solar cell, including: providing a substrate having a first surface and a second surface opposite to each other forming a first doped layer on the second surface and concurrently forming a second doped layer on a target doped dielectric layer; patterning the second doped layer, including removing portions of the second doped layer; etching away the portion of the target doped dielectric layer over the first region; etching away a portion of the target doped semiconductor layer over the first region, and etching away a portion of the second doped layer over the second region; and etching away the portion of the target doped dielectric layer over the second region, a portion of the target doped semiconductor layer over the second region being reserved as a doped semiconductor portion. The respective first regions and the respective second regions are alternatingly distributed.
